Installation of pump
5.1 Positioning
The following must be observed:
The pump must be positioned so that the suction pipe is as short as
possible and there is a sloping gradient towards the suction port of
the pump.
Keep the number of valves, bends and tee-pieces on the suction
side to an absolute minimum.
There must be sufficient space around the pump for piping and
access for maintenance.
5.2
Lining up the pipe system
Ensure that the pipe system is adequately underpinned with pipe
supports so that the pump body is not subject to strain from or the
weight of the pipe system.
Caution!
During the suction process, the pump may tend
to vibrate. A pipe support should be placed close
to the pump suction to prevent pipework vibration
creating excessive noise.
5.3
Power supply
The motor must be connected via a control cabinet to the network in
compliance with the local regulations. Moreover, the motor must be
connected in accordance with the instructions indicated in the inner
side of the connecting box lid of the motor.
The motor should be connected in such a way that the motor and
therefore the impeller are anti-clockwise when viewed from the front
in the direction of the suction port of the pump body. (Fig. 4).
5.4
Liquid supply for flushed shaft seal
Pumps with a flushed shaft seal are fitted with two PTFE hose
connectors on the sealing flange. The hose connectors are 1/8 inch
and fit 6.0 mm hoses. The required flow quantity amounts to 15–30 l/h.
The maximum permissible pressure is 7 bar.
The hose connection should always be positioned vertically with
the fluid inlet below and the outlet above (Fig. 5).
Fluid consumption can be limited by installing a solenoid valve on
the supply side. The open/close function of the solenoid valve can
be controlled by the pump's start/stop sequence.
Do not use steam or steam condensate on the connection for
flushing liquids. If you wish to use steam as a sealant, a special
aseptic pipe connector must be used.
For connectors see 5.5.
5.5
Connecting steam and steam condensate for aseptic use
When static double seals are used, the connection for steam or
steam condensate at the pump body is provided with fittings for
8 mm stainless steel pipes.
Steam of up to 150°C and 5 bar can be used.
